[Dynamic characteristics of auditory analyzer neurons and their relation to selective-combination mechanisms of...

Neuron responses in the chicken torus and caudal neostriatum to signals with different ecological significance (tones "white" noise, species-specific signals) were studied. It is shown that the frequency band percepted by the acoustic analyzer neurons corresponds to the frequency composition of signals emanated by chickens. Neurons selectively responding to the species-specific signals (song, alarm cries) were found in the forebrain. The specificity of the functional organization of different levels of the acoustic analyzer is considered in the light of the selectively combination principle of the signals integration, which may determine the mechanism of both innate and learned memory.
